Yet in regards to the flying thing referenced in Leviticus 11:20, do you think they comprehended whether it was a fowl or an insect. But as far as written in a language they would comprehend, maybe so.
Yet as far as your analogy using the fly, not to argue the point but I have to disagree with your observation that fly use their front legs to hold, life or carry anything. They do rub them together and other parts of their anatomy to clean themselves, so I get the gist of your comment which also demonstrates that it really isn't that simple. But lets say a fly does use its front legs to pick something up, it would be incapable of going upon all four, which is now referred unto as producing 'locomotion'.
Now it can be observed in the format of the passage that there is an introduction statement and a statement of conclusion for the kind of thing being discussed within those two points.
Leviticus 11:2 begins with the beasts which man can eat
Leviticus 11:8 concludes the section on the beasts with
Leviticus 11:9 begins with that which shall can be eaten of all that are in the waters:
Leviticus 11:12 concludes with whatsoever hath no fins nor scales in the waters, that shall be an abomination unto you.
Leviticus 11:13 beings with these are they which ye shall have in abomination among the fowls;
Leviticus 11:20 ends with all fowls that creep, going upon all four, shall be an abomination unto you.
So as Leviticus 11:20 concludes the passages regarding the fowls, thus in Leviticus 11:21 begins the section regarding the creeping things that fly, which refers insects being invertebrates. Thus, it is written "Yet these may ye eat of every flying creeping thing that goeth upon all four, which have legs above their feet, to leap withal upon the earth;" When someone mention the praying mantis, the reason I asked if they had legs above their feet since the passage regarding the creeping things that fly concludes in Leviticus 11:23, "But all other flying creeping things, which have four feet, shall be an abomination unto you."
Since the purpose of the Gospel was not just that all men [male or female] would be saved, as written in 1 Tim 2:1-4
1 I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men;
2 For kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty.
3 For this is good and acceptable in the sight of God our Saviour;
4 Who will have all men to be saved, and to come unto the knowledge of the truth.
So any ideas about what fowl goes upon all four?
